foregoing, wherever located; 
 (b) All inventory now owned or hereafter acquired, including, without limitation,

 (c) All contract rights and general intangibles (excluding Intellectual Property), now owned or hereafter

however, that the Collateral shall include all accounts receivables, accounts, and general intangibles that consist of rights to payment and proceeds from the sale, licensing or disposition of all or any part, or rights in, the foregoing (the
“Rights to Payment”). Notwithstanding the foregoing, if a judicial authority (including a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property is necessary to have a security interest in the
Rights to Payment, then the Collateral shall automatically, and effective as of the Closing Date, include the Intellectual Property to the extent necessary to permit perfection of Lender’s security interest solely with respect to the Rights to
Payment. 
 4.2 After-Acquired Property. If Borrower shall at any time acquire a commercial tort claim, as
defined in the Code, Borrower shall immediately notify Lender in writing signed by Borrower of the brief details thereof and grant to Lender in such writing a security interest therein and in the proceeds thereof, all upon the terms of this
Agreement, with such writing to be in form and substance satisfactory to Lender. 
 4.3 Duration of Security
Interest. Lender’s security interest in the Collateral shall continue until the payment in full and the satisfaction of all Obligations and termination of Lender’s commitment to fund any Loans, whereupon such security interest shall
terminate. Lender shall, at Borrower’s sole cost and expense, execute such further documents and take such further actions as may be reasonably necessary to make effective the release contemplated by this Section 4.3, including duly
executing and delivering termination statements for filing in all relevant jurisdictions under the Code. 
 4.4
Location and Possession of Collateral. The Collateral is and shall remain in the possession of Borrower at its location listed on the cover page hereof or as set forth in the Disclosure Schedule or such other locations which Borrower has
identified in writing to Lender. Borrower shall remain in full possession, enjoyment and control of the Collateral (except only as may be otherwise required by Lender for perfection of its security interest therein) and so long as no Event of
Default has occurred, shall be entitled to manage, operate and use the same and each part thereof with the rights and franchises appertaining thereto; provided that the possession, enjoyment, control and use of the Collateral shall at
all time be subject to the observance and performance of the terms of this Agreement. 
 4.5 Delivery of
Additional Documentation Required. Borrower shall from time to time execute and deliver to Lender, at the request of Lender, all financing statements and other documents Lender may reasonably request, in form satisfactory to Lender, to perfect
and continue Lender’s perfected security interests in the Collateral and in order to consummate fully all of the transactions contemplated under the Loan Documents. 
  


 15 








 4.6 Right to Inspect. Lender (through any of its officers, employees,
or agents) shall have the right, upon reasonable prior notice, from time to time during Borrower’s usual business hours, to inspect Borrower’s books and records and to make copies thereof and to inspect, test, and appraise the Collateral
in order to verify Borrower’s financial condition or the amount, condition of, or any other matter relating to, the Collateral. 
 4.7 Protection of Intellectual Property. Borrower shall (i) protect, defend and maintain the validity and enforceability of its Intellectual Property material to Borrower’s business, to
the extent that failure to do so would have a material adverse effect on Borrower’s business, and (ii) not allow any Intellectual Property material to Borrower’s business to be abandoned, forfeited or dedicated to the public other
than in the ordinary course of business. Borrower’s obligations under this section shall be subject to Borrower’s good faith determination as to whether and in what manner Borrower should exercise its obligations, including as to whether
and in what manner legal proceedings should be pursued. 
 4.8 Lien Subordination. Lender agrees that the
Liens granted to it hereunder in Third Party Equipment shall be subordinate to the Liens of current and future lenders providing equipment financing and equipment lessors for equipment and other personal property acquired by Borrower after the date
hereof (“Third Party Equipment”); provided that such Liens are confined solely to the equipment so financed and the proceeds thereof and are Permitted Liens. Notwithstanding the foregoing, the Obligations hereunder
shall not be subordinate in right of payment to any obligations to other lenders, equipment lenders or equipment lessors and Lender’s rights and remedies hereunder in the Collateral which does not constitute Third Party Equipment shall not in
any way be subordinate to the rights and remedies of any such lenders or equipment lessors. So long as no Event of Default has occurred which has not been waived by Lender, Lender agrees to execute and deliver such agreements and documents as may be
reasonably requested by Borrower from time to time which set forth the lien subordination described in this Section 4.8 and are reasonably acceptable to Lender. Lender shall have no obligation to execute any agreement or document which
would impose obligations, restrictions or lien priority on Lender which are less favorable to Lender than those described in this Section 4.8. 
 5. Representations and Warranties. Except as set forth in the Disclosure Schedule, Borrower represents and warrants as follows:

Section 5.3 to the Disclosure Schedule, neither the execution and delivery of any Loan Document to which Borrower is a party nor the consummation of the transactions therein contemplated nor compliance with the terms, conditions and provisions
thereof will conflict with or result in a breach of any of the terms, conditions or provisions of the certificate of incorporation, the by-laws, or any other organizational documents of Borrower or any law or any regulation, order, writ, injunction
or decree of any court or governmental instrumentality or any material agreement or instrument to which Borrower is a party or by which it or any of its Property is bound or to which it or any of its Property is subject, or constitute a default

Authorization; Enforceability. The execution and delivery of this Agreement, the granting of the security interest in the Collateral, the incurring of the Loans, the execution and delivery of the other Loan Documents to which Borrower is a
party and the consummation of the transactions herein and therein contemplated have each been duly authorized by all necessary action on the part of Borrower. No authorization, consent, approval, license or exemption of, and no registration,
qualification, designation, declaration or filing with, or notice to, any Person is, was or will be necessary to (i) the valid execution and delivery of any Loan Document to which Borrower is a party, (ii) the performance of
Borrower’s obligations under any Loan Document, or (iii) the granting of the security interest in the Collateral, except for filings in connection with the perfection of the security interest in any of the Collateral or the issuance of the
Warrant. The Loan Documents have been duly executed and delivered and constitute legal, valid and binding obligations of Borrower, enforceable in accordance with their respective terms, except as the enforceability thereof may be limited by
bankruptcy, insolvency or other similar laws of general application relating to or affecting the enforcement of creditors’ rights or by general principles of equity. 
 5.5 No Prior Encumbrances. Borrower has good and marketable title to the Collateral, free and clear of Liens except
for Permitted Liens. Borrower has good title and ownership of, or is licensed under, all of Borrower’s current Intellectual Property. Borrower has not received any written communications alleging that Borrower has violated, or by conducting its
business as proposed, would violate any proprietary rights of any other Person. Borrower has no knowledge of any infringement or violation by it of the intellectual property rights of any third party and has no knowledge of any violation or
infringement by a third party of any of its Intellectual Property. The Collateral and the Intellectual Property constitute substantially all of the assets and property of Borrower. 
 5.6 Name; Location of Chief Executive Office, Principal Place of Business and Collateral. Borrower has not done
business under any name other than that specified on the signature page hereof. Borrower’s jurisdiction of incorporation, chief executive office, principal place of business, and the place where Borrower maintains its records concerning the

exists which would reasonably be expected to have a material adverse effect on the financial condition, business or operations of Borrower since December 31, 2007. 
 5.10 Full Disclosure. No representation, warranty or other statement made by Borrower in any Loan Document (including
the Disclosure Schedule), certificate or written statement furnished to Lender contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained in such certificates or statements
not misleading. There is no fact known to Borrower which materially adversely affects, or which would in the future be reasonably expected to materially adversely affect, its ability to perform its obligations under this Agreement. 
 5.11 Solvency, Etc. Borrower is Solvent (as defined below) and, after the execution and delivery of the Loan
Documents and the consummation of the transactions contemplated thereby, Borrower will be Solvent. “Solvent” means, with respect to any Person on any date, that on such date (a) the fair value of the property of such Person is
greater than the fair value of the liabilities (including, without limitation, contingent liabilities) of such Person, (b) the present fair saleable value of the assets of such Person is not less than the amount that will be required to pay the
probable liability of such Person on its debts as they become absolute and matured, (c) such Person does not intend to, and does not believe that it will, incur debts or liabilities beyond such Person’s ability to pay as such debts and
liabilities mature and (d) such Person is not engaged in business or a transaction, and is not about to engage in business or a transaction, for which such Person’s property would constitute an unreasonably small capital. 
 5.12 Subsidiaries. Borrower has no Subsidiaries. 
 5.13 Catastrophic Events; Labor Disputes. None of Borrower or its properties is or has been affected by any

Consultants. 
 (a) No Violation. To the knowledge of Borrower, no officer, employee or
consultant of Borrower is, or is now expected to be, in violation of any term of any employment contract, proprietary information agreement, nondisclosure agreement, noncompetition agreement or any other material contract or agreement or any
restrictive covenant relating to the right of any such officer, employee or consultant to be employed by Borrower because of the nature of the business conducted or to be conducted by Borrower or relating to the use of trade secrets or proprietary
information of others, and to Borrower’s knowledge, the continued employment of Borrower’s officers, employees and consultants does not subject Borrower to any material liability for any claim or claims arising out of or in connection with
any such contract, agreement, or covenant. 
 (b) No Present Intention to Terminate. To the knowledge of
Borrower, no officer of Borrower, and no employee or consultant of Borrower whose termination, either individually or in the aggregate, would reasonably be expected to have a material adverse effect on the financial condition, business or operations

keep, maintain, repair, replace and operate such leased equipment in accordance with the terms of the applicable lease.

(30) days of Borrower becoming aware thereof. 
 8.11 Unenforceable Loan Document. If (a) any
Loan Document shall in any material respect cease to be a legal, valid and binding obligation of Borrower enforceable in accordance with its terms so as to deprive Lender of the practical realization of the principal benefits provided by the Loan
Documents, or (b) Borrower shall assert that any Loan Document is not a legal, valid and binding obligation of Borrower enforceable in accordance with its terms. 
 8.12 Involuntary Insolvency Proceeding. If a proceeding shall have been instituted in a court having jurisdiction in
the premises seeking a decree or order for relief in respect of Borrower in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or for the appointment of a receiver, liquidator, assignee,
custodian, trustee (or similar official) of Borrower or for any substantial part of its Property, or for the winding-up or liquidation of its affairs, and such proceeding shall remain undismissed or unstayed and in effect for a period of sixty
(60) consecutive days or such court shall enter a decree or order granting the relief sought in such proceeding. 
 8.13 Voluntary Insolvency Proceeding. If Borrower shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, shall consent to the entry of an order for relief in an
involuntary case under any such law, or shall consent to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian (or other similar official) of Borrower or for any substantial part of its Property, or shall
make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due, or shall take any corporate action in furtherance of any of the foregoing. 
 9. Lender’s Rights and Remedies. 
 9.1 Rights and Remedies. Upon the occurrence of any Default or Event of Default and during the continuance thereof, Lender shall not have any further obligation to advance money or extend credit to
or for the benefit of Borrower. In addition, upon the occurrence of an Event of Default and during the continuance thereof, Lender shall have the rights, options, duties and remedies of a secured party as permitted by law and, in addition to and
without limitation of the foregoing, Lender may, at its election, without notice of election and without demand, do any one or more of the following, all of which are authorized by Borrower: 
 (a) Acceleration of Obligations. Declare all Obligations, whether evidenced by this Agreement, by any of the other
Loan Documents, or otherwise, including (i) all accrued and unpaid Scheduled Payments with respect to each Loan, (ii) any accrued and unpaid interest, (iii) the amounts which would have otherwise come due under
Section 2.3(b)(iii) if the Loans had been voluntarily prepaid, (iv) the unpaid principal balance of the Loans and (v) all other sums, if any, that shall have become due and payable hereunder, immediately due and payable
(provided that upon the occurrence of an Event of Default described in Section 8.12 or 8.13 all Obligations shall become immediately due and payable without any action by Lender); 
  

 25 








 (b) Protection of Collateral. Make such payments and do such acts as
Lender considers necessary or reasonable to protect Lender’s security interest in the Collateral. Borrower agrees to assemble the Collateral if Lender so requires and to make the Collateral available to Lender as Lender may designate. Borrower
authorizes Lender and its designees and agents to enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any Lien which in Lender’s
determination appears or is claimed to be prior or superior to its security interest and to pay all reasonable expenses incurred in connection therewith. With respect to any of Borrower’s owned premises, Borrower hereby grants Lender a license
to enter into possession of such premises and to occupy the same, without charge, for up to one hundred twenty (120) days in order to exercise any of Lender’s rights or remedies provided herein, at law, in equity, or otherwise; 

(c) Preparation of Collateral for Sale. Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale,
advertise for sale, and sell (in the manner provided for herein) the Collateral. Lender and its agents and any purchasers at or after foreclosure are hereby granted a non-exclusive, irrevocable, perpetual, fully paid, royalty-free license or other
right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrower’s Intellectual Property, including without limitation, labels, patents, copyrights, rights of use of any name, trade secrets, trade
names, trademarks, service marks, and advertising matter, or any Property of a similar nature, now or at any time hereafter owned or acquired by Borrower or in which Borrower now or at any time hereafter has any rights; provided that
such license shall only be exercisable in connection with the disposition of Collateral upon Lender’s exercise of its remedies hereunder and shall automatically terminate upon the disposition of the Collateral; 
 (d) Sale of Collateral. Sell the Collateral at either a public or private sale, or both, by way of one or more
contracts or transactions, for cash or on terms, in such manner and at such places (including Borrower’s premises) as Lender determines are commercially reasonable and otherwise in accordance with applicable law; and 
 (e) Purchase of Collateral. Credit bid and purchase all or any portion of the Collateral at any public sale.

 Any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Borrower. 
 9.2 Set Off Right. Upon the occurrence and during the continuance of any Event of Default, Lender may set off and
apply to the Obligations any and all indebtedness at any time owing to or for the credit or the account of Borrower or any other assets of Borrower in Lender’s possession or control. 
  

 26 








 9.3 Effect of Sale. Upon the occurrence of an Event of Default, to
the extent permitted by law, Borrower covenants that it will not at any time insist upon or plead, or in any manner whatsoever claim or take any benefit or advantage of, any stay or extension law now or at any time hereafter in force, nor claim,
take nor insist upon any benefit or advantage of or from any law now or hereafter in force providing for the valuation or appraisement of the Collateral or any part thereof prior to any sale or sales thereof to be made pursuant to any provision
herein contained, or to the decree, judgment or order of any court of competent jurisdiction; nor, after such sale or sales, claim or exercise any right under any statute now or hereafter made or enacted by any state or otherwise to redeem the
property so sold or any part thereof, and, to the full extent legally permitted, except as to rights expressly provided herein, hereby expressly waives for itself and on behalf of each and every Person, except decree or judgment creditors of
Borrower, acquiring any interest in or title to the Collateral or any part thereof subsequent to the date of this Agreement, all benefit and advantage of any such law or laws, and covenants that it will not invoke or utilize any such law or laws or
otherwise hinder, delay or impede the execution of any power herein granted and delegated to Lender, but will suffer and permit the execution of every such power as though no such power, law or laws had been made or enacted. Any sale, whether under
any power of sale hereby given or by virtue of judicial proceedings, shall operate to divest all right, title, interest, claim and demand whatsoever, either at law or in equity, of Borrower in and to the Property sold, and shall be a perpetual bar,
both at law and in equity, against Borrower, its successors and assigns, and against any and all Persons claiming the Property sold or any part thereof under, by or through Borrower, its successors or assigns. 
 9.4 Power of Attorney in Respect of the Collateral. Borrower does hereby irrevocably appoint Lender (which appointment
is coupled with an interest), the true and lawful attorney in fact of Borrower with full power of substitution, for it and in its name to file any notices of security interests, financing statements and continuations and amendments thereof pursuant
to the Code or federal law, as may be necessary to perfect, or to continue the perfection of Lender’s security interests in the Collateral. Borrower does hereby irrevocably appoint Lender (which appointment is coupled with an interest) on the
occurrence and during the continuance of an Event of Default, the true and lawful attorney in fact of Borrower with full power of substitution, for it and in its name: (a) to ask, demand, collect, receive, receipt for, sue for, compound and
give acquittance for any and all rents, issues, profits, avails, distributions, income, payment draws and other sums in which a security interest is granted under Section 4 with full power to settle, adjust or compromise any claim
thereunder as fully as if Lender were Borrower itself; (b) to receive payment of and to endorse the name of Borrower to any items of Collateral (including checks, drafts and other orders for the payment of money) that come into Lender’s
possession or under Lender’s control; (c) to make all demands, consents and waivers, or take any other action with respect to, the Collateral; (d) in Lender’s discretion to file any claim or take any other action or proceedings,
either in its own name or in the name of Borrower or otherwise, which Lender may reasonably deem necessary or appropriate to protect and preserve the right, title and interest of Lender in and to the Collateral; (e) endorse Borrower’s name
on any checks or other forms of payment or security; (f) sign Borrower’s name on any invoice or bill of lading for any account or drafts against account debtors; (g) make, settle, and adjust all claims under Borrower’s insurance
policies; (h) settle and adjust disputes and claims about the accounts directly with account debtors, for amounts and on terms Lender determines reasonable; (i) transfer the Collateral into the name of Lender or a third party as the Code
permits; and (j) to otherwise act with respect thereto as though Lender were the outright owner of the Collateral. 
  

 27 








 9.5 Lender’s Expenses. If Borrower fails to pay any amounts or
furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then Lender may do any or all of the following: (a) after five (5) Business Days’ prior written notice of
Lender’s intention to do so, make payment of the same or any part thereof; or (b) obtain and maintain insurance policies of the type discussed in Section 6.8 of this Agreement, and take any action with respect to such policies
as Lender deems prudent. Any amounts so paid or deposited by Lender shall constitute Lender’s Expenses, shall be immediately due and payable, shall bear interest at the Default Rate and shall be secured by the Collateral. Any payments made by
Lender shall not constitute an agreement by Lender to make similar payments in the future or a waiver by Lender of any Event of Default under this Agreement. Borrower shall pay all reasonable fees and expenses, including without limitation,
Lender’s Expenses, incurred by Lender in the enforcement or attempt to enforce any of the Obligations hereunder not performed when due. 
 9.6 Remedies Cumulative. Lender’s rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Lender shall have all other rights and remedies
not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Lender of one right or remedy shall be deemed an election, and no waiver by Lender of any Event of Default on Borrower’s part shall be deemed a
continuing waiver. No delay by Lender shall constitute a waiver, election, or acquiescence by it. 
 9.7
Application of Collateral Proceeds. The proceeds and/or avails of the Collateral, or any part thereof, and the proceeds and the avails of any remedy hereunder (as well as any other amounts of any kind held by Lender, at the time of or
received by Lender after the occurrence of an Event of Default hereunder) shall be paid to and applied as follows: 
 (a) First, to the payment of out-of-pocket costs and expenses, including all amounts expended to preserve the value of the Collateral, of foreclosure or suit, if any, and of such sale and the exercise of any other rights or remedies,
and of all proper fees, expenses, liability and advances, including reasonable legal expenses and attorneys’ fees, incurred or made hereunder by Lender, including, without limitation, Lender’s Expenses; 
 (b) Second, to the payment to Lender of the amount then owing or unpaid on the Loans for Scheduled Payments, any
accrued and unpaid interest, the amounts which would have otherwise come due under Section 2.3(b)(iii), if the Loans had been voluntarily prepaid, the principal balance of the Loans, and all other Obligations with respect to the Loans
(provided, however, if such proceeds shall be insufficient to pay in full the whole amount so due, owing or unpaid upon the Loans, then to the unpaid interest thereon, then to the amounts which would have otherwise come due under
Section 2.3(b)(iii), if the Loans had been voluntarily prepaid, then to the principal balance of the Loans, and then to the payment of other amounts then payable to Lender under any of the Loan Documents); and 
 (c) Third, to the payment of the surplus, if any, to Borrower, its successors and assigns, or to the Person lawfully
entitled to receive the same. 
  

 28 








 9.8 Reinstatement of Rights. If Lender shall have proceeded to
enforce any right under this Agreement or any other Loan Document by foreclosure, sale, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely, then and in every such
case (unless otherwise ordered by a court of competent jurisdiction), Lender shall be restored to its former position and rights hereunder with respect to the Property subject to the security interest created under this Agreement. If Lender at any
time after it has accelerated the Loans chooses in its sole discretion to declare the acceleration void and reinstate the Loans, Borrower and Lender shall thereafter continue to be governed by the terms and conditions of the Loan Document as if such
acceleration had not occurred. 
 10. Waivers; Indemnification. 
 10.1 Demand; Protest. Except as expressly set forth in any Loan Document, Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees at any
time held by Lender on which Borrower may in any way be liable. 
 10.2 Lender’s Liability for
Collateral. So long as Lender complies with its obligations, if any, under the Code, Lender shall not in any way or manner be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage thereto occurring or
arising in any manner or fashion from any cause other than Lender’s gross negligence or willful misconduct; (c) any diminution in the value thereof; or (d) any act or default of any carrier, warehouseman, bailee, forwarding agency, or
other Person whomsoever. All risk of loss, damage or destruction of the Collateral shall be borne by Borrower. 
 10.3 Indemnification and Waiver. Whether or not the transactions contemplated hereby shall be consummated: 
 (a) General Indemnity. Borrower agrees upon demand to pay or reimburse Lender for all liabilities, obligations and out-of-pocket expenses, including Lender’s Expenses and reasonable fees and
expenses of counsel for Lender from time to time arising in connection with the enforcement or collection of sums due under the Loan Documents, and in connection with any amendment or modification of the Loan Documents or any “work-out” in
connection with the Loan Documents. Borrower shall indemnify, reimburse and hold Lender, and each of its respective successors, assigns, agents, attorneys, officers, directors, shareholders, servants, agents and employees (each an
“Indemnified Person”) harmless from and against all liabilities, losses, damages, actions, suits, demands, claims of any kind and nature (including claims relating to environmental discharge, cleanup or compliance), all costs and
expenses whatsoever to the extent they may be incurred or suffered by such Indemnified Person in connection therewith (including reasonable attorneys’ fees and expenses), fines, penalties (and other charges of any applicable Governmental
Authority), licensing fees relating to any item of Collateral, damage to or loss of use of property (including consequential or special damages to third parties or damages to Borrower’s property), or bodily injury to or death of any person
(including any agent or employee of Borrower) (each, a “Claim”), directly or indirectly relating to or arising out of the use of the proceeds of the Loans or otherwise, the falsity of any representation or warranty of

  

 29 








 
Borrower or Borrower’s failure to comply with the terms of this Agreement or any other Loan Document. The foregoing indemnity shall cover, without limitation, (i) any Claim in
connection with a design or other defect (latent or patent) in any item of equipment or product included in the Collateral, (ii) any Claim for infringement of any patent, copyright, trademark or other intellectual property right, (iii) any
Claim resulting from the presence on or under or the escape, seepage, leakage, spillage, discharge, emission or release of any Hazardous Materials on the premises owned, occupied or leased by Borrower, including any Claims asserted or arising under
any Environmental Law, (iv) any Claim for negligence or strict or absolute liability in tort, or (v) any Claim asserted as to or arising under any Account Control Agreement or any Landlord Agreement; provided, however,
Borrower shall not indemnify Lender for any liability incurred by Lender as a direct and sole result of Lender’s gross negligence or willful misconduct or any Claim arising from (i) Lender’s disposition of any Collateral which was
still a work-in-process at the time Lender took control of such Collateral, or (ii) any Collateral altered after Lender took control of such Collateral. Such indemnities shall continue in full force and effect, notwithstanding the expiration or
termination of this Agreement. Upon Lender’s written demand, Borrower shall assume and diligently conduct, at its sole cost and expense, the entire defense of Lender, each of its partners, and each of their respective, agents, employees,
directors, officers, shareholders, successors and assigns against any indemnified Claim described in this Section 10.3(a). Borrower shall not settle or compromise any Claim against or involving Lender without first obtaining
Lender’s written consent thereto, which consent shall not be unreasonably withheld; provided, that Borrower may settle Claims which require the payment of monetary damages only, without Lender’s consent, so long as Borrower obtains a
general release of all claims against Lender. 
 (b) Waiver. NOTWITHSTANDING ANYTHING TO THE CONTRARY
CONTAINED IN THIS AGREEMENT OR ANYWHERE ELSE, EACH OF BORROWER AND LENDER AGREES THAT IT SHALL NOT SEEK FROM THE OTHER UNDER ANY THEORY OF LIABILITY (INCLUDING ANY THEORY IN TORTS), ANY SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES.

 (c) Survival; Defense. The obligations in this Section 10.3 shall survive payment of all
other Obligations pursuant to Section 12.8. At the election of any Indemnified Person, Borrower shall defend such Indemnified Person using legal counsel satisfactory to such Indemnified Person in such Person’s reasonable discretion,
at the sole cost and expense of Borrower. All amounts owing under this Section 10.3 shall be paid within thirty (30) days after written demand.

granted or withheld in Lender’s sole discretion. Lender shall have the right without the consent of or notice to Borrower to sell, transfer, assign, negotiate, or grant participations in all or any part of, or any interest in Lender’s
rights and benefits hereunder, provided that such sale, transfer, assignment, negotiation, or participation is not to a competitor of the Borrower. Lender will endeavor to give notice of the same to Borrower, but failure to do so shall not affect

 12.2 Time of Essence. Time is of the essence for the performance of
all obligations set forth in this Agreement. 
 12.3 Severability of Provisions. Each provision of this
Agreement shall be several from every other provision of this Agreement for the purpose of determining the legal enforceability of any specific provision. 
 12.4 Entire Agreement; Construction; Amendments and Waivers. 
 (a) Entire Agreement. This Agreement and each of the other Loan Documents dated as of the date hereof, taken together, constitute and contain the entire agreement between Borrower and Lender and supersede any and all prior
agreements, negotiations, correspondence, understandings and communications between the parties, whether written or oral, respecting the subject matter hereof. Borrower acknowledges that it is not relying on any representation or agreement made by
Lender or any employee, attorney or agent thereof, other than the specific agreements set forth in this Agreement and the Loan Documents. 
 (b) Construction. This Agreement is the result of negotiations between and has been reviewed by each of Borrower and Lender executing this Agreement as of the date hereof and their respective
counsel; accordingly, this Agreement shall be deemed to be the product of the parties hereto, and no ambiguity shall be construed in favor of or against Borrower or Lender. Borrower and Lender agree that they intend the literal words of this
Agreement and the other Loan Documents and that no parol evidence shall be necessary or appropriate to establish Borrower’s or Lender’s actual intentions. 
 (c) Amendments and Waivers. Any and all amendments, modifications, discharges or waivers of, or consents to any
departures from any provision of this Agreement or of any of the other Loan Documents shall not be effective without the written consent of Lender. Any waiver or consent with respect to any provision of the Loan Documents shall be effective only in
the specific instance and for the specific purpose for which it was given. No notice to or demand on Borrower in any case shall entitle Borrower to any other or further notice or demand in similar or other circumstances. Any amendment, modification,
waiver or consent affected in accordance with this Section 12.4 shall be binding upon Lender and on Borrower. 
 12.5 Reliance by Lender. All covenants, agreements, representations and warranties made herein by Borrower shall be deemed to be material to and to have been relied upon by Lender, notwithstanding
any investigation by Lender. 
 12.6 No Set-Offs by Borrower. All sums payable by Borrower pursuant to
this Agreement or any of the other Loan Documents shall be payable without notice or demand and shall be payable in United States Dollars without set-off or reduction of any manner whatsoever.

counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement. 
  

 32 








 12.8 Survival. All covenants, representations and warranties made in
this Agreement shall continue in full force and effect so long as any Obligations or commitment to fund remain outstanding. The obligations of Borrower to indemnify Lender with respect to the expenses, damages, losses, costs and liabilities
described in Section 10.3 shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Lender have run. 
 13. Relationship of Parties. Borrower and Lender acknowledge, understand and agree that the relationship between Borrower, on the one
hand, and Lender, on the other, is, and at all time shall remain solely that of a borrower and lender. Lender shall not under any circumstances be construed to be a partner or a joint venturer of Borrower or any of its Affiliates; nor shall Lender
under any circumstances be deemed to be in a relationship of confidence or trust or a fiduciary relationship with Borrower or any of its Affiliates, or to owe any fiduciary duty to Borrower or any of its Affiliates. Lender does not undertake or
assume any responsibility or duty to Borrower or any of its Affiliates to select, review, inspect, supervise, pass judgment upon or otherwise inform Borrower or any of its Affiliates of any matter in connection with its or their Property, any
Collateral held by Lender or the operations of Borrower or any of its Affiliates. Borrower and each of its Affiliates shall rely entirely on their own judgment with respect to such matters, and any review, inspection, supervision, exercise of
judgment or supply of information undertaken or assumed by Lender in connection with such matters is solely for the protection of Lender and neither Borrower nor any Affiliate is entitled to rely thereon. 
 14. Confidentiality. All information (other than periodic reports filed by Borrower with the Securities and Exchange Commission)
disclosed by Borrower to Lender in writing or through inspection pursuant to this Agreement that is marked confidential or a reasonable person would deem confidential shall be considered confidential. Lender agrees to use the same degree of care to
safeguard and prevent disclosure of such confidential information as Lender uses with its own confidential information, but in any event no less than a reasonable degree of care. Lender shall not disclose such information to any third party (other
than to Lender’s partners, attorneys, governmental regulators, or auditors, or to Lender’s subsidiaries and affiliates and prospective transferees and purchasers of the Loans, all subject to the same confidentiality obligation set forth
herein or as required by law, regulation, subpoena or other order to be disclosed) and shall use such information only for purposes of evaluation of its investment in Borrower and the exercise of Lender’s rights and the enforcement of its
remedies under this Agreement and the other Loan Documents. The obligations of confidentiality shall not apply to any information that (a) was known to the public prior to disclosure by Borrower under this Agreement, (b) becomes known to
the public through no fault of Lender, (c) is disclosed to Lender by a third party having a legal right to make such disclosure, or (d) is independently developed by Lender. Notwithstanding the foregoing, Lender’s agreement of
confidentiality shall not apply if Lender has acquired indefeasible title to any Collateral or in connection with any enforcement or exercise of Lender’s rights and remedies under this Agreement following an Event of Default, including the
enforcement of Lender’s security interest in the Collateral. 
  

 33 








 15. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER. THIS AGREEMENT SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF CONNECTICUT, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. EACH OF BORROWER AND LENDER HEREBY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS LOCATED
